This essay argues that the practice ofmedicine is not a phronetic activity in theoriginal Aristotelian sense of that term. Jonsen andToulmin are two philosophers who have conflated thetechne of medicine with phronesis. Thisconflation ignores Aristotle's crucial distinctionbetween techne and phronesis and his useof the medical analogy. It is argued that medicalreasoning is similar to phronesis but does notexemplify it. Phronesis will not save thelife of medical ethics. The concept could be utilized as amoral prosthetic.
